PEBAMBULATOR.

Application filed December 28, 1918.

To all whom it may concern:

Be it known that I, ALEXANDER B. LEITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Perambulators, of which the following is'a specification.

This invention relates particularly to perambulators, or go-carts; and the primary object is to provide a simple and durable construction, eliminating, as far as possible, the use of steel. 7

The invention is illustrated, in its preferred embodiment, in the accompanying drawings, in whicha Figure 1 represents a side elevational view of a perambulator constructed in accordance. withv the invention, one pair of wheels being removed from the axles; and Fig. 2, a horizontal sectional view taken as indicated at line 2 of Fig. 1.

In the construction illustrated, A repreear-frame; B, a seat mounted thereon; (I, a folding back mounted on the seat; and D, a folding superstructure mounted on the running gear-frame, and comprising, as a part thereof, a folding handle D In the preferred construction, the running gear-frame A comprises a pair of longitudinal wooden side-members A front and rear Y-form axle-supports A and A, respectively, rigidly connected with each sidemember; axles A carried by the lower ends of the brackets, or supports; and wheels A journaled on the extremities of the axles. The side-members A are cross-connected by a rear bar A and an intermediate bar A, which serve to support springs B upon which the seat B is mounted.

Each front axle-support, or bracket, A comprises a forwardly and downwardly-inclined bar 1 anda rearwardly and down wardly-inclined bar 2, which are joined together near. their lower ends, thus affording a bracket of general Y-form. The member 1 has an upper extension 1 which projects above the corresponding side-member A of the frame and serves to support one of the pivots for the folding superstructure D; and the member 1 has a lower extension 7) which projects below the member 2 and serves to support the axle A. The member 2 has an upward extension 2 which projects Specification of Letters Patent.

above the side-member A and the lower extremity 2 of the member 2 crosses the member 1 a short distance above the axle. The members 1 and 2 are disposed inside of the side-member A At the points where the members 1 and 2 cross the side-members A the members 1 and 2 are recessed at their outer sides to receive the member A and the member A is recessed at its inner side to receive the members 1 and 2. In other words, the members are mortised together; and a secure connection is effected by means of bolts 3. In a corresponding manner, the members 1 and 2, where they cross each other, are recessed at their adjacent sides and fitted together by suitable mortising;

I and a secure connection is afforded by means of a bolt 4:. The members 1 and 2 comprise wooden bars; and the lower extension 6 of the members 1 are provided with perforations to receive the axle A. The extensions b are also provided with slits 5, thus producing forked extremities; and these forks are connected by clamping bolts 6, which serve to clamp the extensions 6 upon the axle. In other words, the extensions 1) comprise split ends equipped with clamping bolts, so that the axle may be firmly secured by means of this simple expedient.

The upward extensions 2 of the members 2 are connected by a cross-bar 7, which may comprise a round of wood, secured between the extensions 2 by means of screws 8, as shown in Fig. 2. A foot-supporting pocket 9 is formed by connecting a ply of fabric, or leather, with the bar 7 and the front portion of the seat B.

Each rear axle. support A comprises a forwardly and downwardly-inclined bar 10 having an upward extension 10 projecting above the side-member A and affording a support for the handle-pivot; and a rearwardly and downwardly-inclined member 11 having the upper end secured, by a bolt 11, to the side-member A and having a lower extension 11 projecting below the member 10 and affording a support for the rear axle A The members 10 and 11 are disposed in the side of the side-member A and have mortised connection therewith, in a manner described with reference to the front axlesupports. The members 10 are firmly secured to the members A by means of bolts 10". At the point where the members 10 and 11 cross each other, they are mortised on.

. ning gear-fraine through the medium of any suitable springs. In the illustration given, the springs B are oflea-f-form and provided with loops to give the desired resiliency, the extremities of the springs being secured to the cross-bars A and A of the running gear-frame, and the intermediate portions 14 of the springs having the seat 13 mounted thereon.

The back C of the seat is connected by hinges 15 at the rear portion of the seat and adapted to fold forwardly upon :the seat. The seat is adapted to be supported in different positions of inclination by means of adjustable blocks 1.6, which are mounted upon rearward extensions 16 of the seat-frame.

tail, as this feature is unimportant in con- 3 nection with the present application.

The" folding superstructure D comprises the handle D whose side-members, or arms, have their'lower end-portions connected, by pivots17, with the upward extensions 1O of the members 10; a pair oflinks 18 having their lower ends connected, by pivots 19, with the upward extensions 1 of the'meinbers 1; and links, or bars, 20, having their front ends connected, by pivots 20, with the upper ends of the links 18, and having their rear ends connected, by pivots 20*, with the intermediate portions of the handle-bars D handle-bars have extensions 21 below the pivots 17, which are adapted to bear against stops 22, with which the rear portions of the V manner. The links 18 and 20, as well as the handle-bars D may be of wood.

bars connected by short links, or joint-members, 23.

From the description given, it will be understood that the structure is chiefly of wood. Aside from the springs, axles, and locking braces, only a few metal parts, such as screws, bolts and hinges, are required.

The construction described is strong, durable, inexpensive, and of pleasing appearance. The structure is also very light. When desired, the wheels may be removed, and the superstructure may be folded upon the running gear-frame for'convenience in shipping. Also, the structure is of the semifolding type, which facilitates the use of the device in traveling.

The foregoing detailed description has The been given for clearness of understanding only, and no unnecessary. limitation'should be understood therefrom, but the appended claims should bejconstrued as broadly as permissible, in view of the prior art.
